The femtosecond laser was recently introduced to cataract surgery in order to replace several highly successful and low risk manual surgical techniques with automated laser techniques. Despite the hope that femtosecond laser-assisted cataract surgery (FLACS) would lead to safer and more predictable surgical outcomes, the literature consistently demonstrates that FLACS has provided no advantage over standard phacoemulsification cataract surgery (SP). Yet, the disadvantages of FLACS as compared to SP are clear. FLACS is more expensive and time-consuming, may increase surgical complications during the surgeon's initial learning period, introduces unique risks due to the additional steps of laser docking and treatment, and is limited in its scope of use as compared to SP due to factors including small pupils and orbital anatomy. While FLACS may one day prove to be advantageous for a small subset of patients, such as those with corneal endothelial cell dysfunction or zonular instability, these patients have not been the targets of this technology, and FLACS will not become the standard technique for cataract extraction in the coming decade.
飞秒激光最近被引入白内障手术中,以自动化激光技术取代几种非常成功且风险较低的手动手术技术。尽管人们希望飞秒激光辅助白内障手术(FLACS)能够带来更安全、更可预测的手术结果,但文献一致表明,FLACS 并未优于标准的超声乳化白内障手术(SP)。然而,与 SP 相比,FLACS 的缺点是显而易见的。FLACS 更昂贵、耗时更长,可能会在外科医生的初始学习期间增加手术并发症,由于激光对接和治疗的额外步骤,会带来独特的风险,并且由于瞳孔小和眼眶解剖等因素,其使用范围比 SP 更有限。虽然 FLACS 有朝一日可能会对一小部分患者(如角膜内皮细胞功能障碍或悬韧带不稳定的患者)有利,但这些患者并不是该技术的目标人群,并且在未来十年内,FLACS 不会成为白内障摘除的标准技术。
